If i can see it right, it would be A because it starts at 30, then rises as the number of rooms increases.
You can check that the limit comes in an undefined form:
In these cases, we can use de l'Hospital rule, and evaluate the limit of the ratio of the derivatives. We have:
and
So, we have
Answer:
y = 4
Step-by-step explanation:
-1y = -4
Divide both sides by -1 to get y by itself.
-1/-1 = -4/-1
y = 4
It's positive because there are two negatives, which mean they cancel out.
1st integer: x
2nd integer: x+2
Multiply them: x(x+2)=440
X^2+2x-440=0
Use the quadratic formula
x=-22 or x=20
Since x must be a positive integer number, x=20.
Answer:
1st: 20.
2nd: 22
